What to do if you have asthma on a plane?
What to do if you have asthma on a plane? The air on planes is very dry, which can trigger an asthma flare-up. Make sure you have your quick-relief inhaler handy and try to drink a lot of water.
Should I fly if I have breathing problems?
Most people with a lung condition can travel safely on planes, but you should talk to your doctor before you make any plans. You may need a fitness-to-fly (hypoxic challenge) test to confirm whether you need in-flight oxygen.
Is flying hard on your lungs?
Low air pressure during air travel also decreases the amount of oxygen in the air. This effect is modest and generally not noticeable for healthy travelers. For patients with significant lung disease, a small decrease in available oxygen can cause significant symptoms, especially with exercise.
